ZEFRETOL 800

• Name: ZEFRETOL 800 (Brand Name)

• Composition: Each ZEFRETOL 800 tablet contains Eslicarbazepine (800 mg) or Eslicarbazepine acetate (800 mg) as the active ingredient.

• Uses: ZEFRETOL 800 is an anti-epileptic medication primarily used to control and prevent epileptic seizures. It is indicated for partial-onset seizures in adults and adolescents, and children above 6 years of age. It can be used as monotherapy in adults with newly diagnosed epilepsy or as an adjunctive therapy alongside other anti-epileptic medicines when seizures are not adequately controlled. It works by stabilizing hyperexcited nerve cells in the brain, blocking voltage-gated sodium channels to reduce abnormal electrical activity.

• Dosage and Administration: ZEFRETOL 800 should be taken orally as prescribed by a doctor, typically once daily, with or without food. Tablets should be swallowed whole with water, not crushed, broken, or chewed. It is important to take the medicine at approximately the same time each day. The dosage may vary based on individual factors like seizure severity and response to treatment. Do not stop taking this medicine suddenly without consulting a doctor, as it may increase seizure frequency.

• Side Effects: Common side effects include dizziness, sleepiness, nausea, headache, fatigue, blurred or double vision, and rash. More serious side effects can include hyponatremia (low sodium levels), which may lead to confusion, fatigue, and muscle weakness, and potential suicidal thoughts.

• Precautions:

  • Pregnancy: Caution is advised during pregnancy, and it should only be used if clearly necessary.
  • Breastfeeding: ZEFRETOL 800 is generally not recommended for use during breastfeeding, as it passes into breast milk and may cause harmful effects to the infant.
  • Alcohol: Avoid alcohol as it may increase side effects like dizziness and drowsiness.
  • Driving/Operating Machinery: May cause dizziness, drowsiness, and blurred vision, so avoid driving or operating heavy machinery until you know how it affects you.
  • Medical Conditions: Use with caution in patients with heart rhythm disorders, kidney problems, and liver impairment. It is contraindicated in severe kidney or liver disease, and in patients with heart rhythm disorders like second- or third-degree atrioventricular (AV) block.
  • Interactions: Inform your doctor about all other medications, including hormonal contraceptives, carbamazepine, oxcarbazepine, phenytoin, phenobarbital, simvastatin, rosuvastatin, warfarin, amitriptyline, diuretics, beta-blockers, and antiarrhythmics, as interactions may occur.
  • Suicidal Ideation: Monitor for signs of suicidal thoughts or behavior.

• Storage: Store ZEFRETOL 800 at room temperature below 30°C in a dry place, protected from direct light and moisture. Keep out of reach of children and pets, and store in its original packaging. Do not use after the expiry date.

ZEFRETOL 800 is a prescription medication manufactured by SUN PHARMA-SEPHIUS DIV, primarily used to manage epilepsy. It contains Eslicarbazepine as its active ingredient.

What is ZEFRETOL 800 used for?

ZEFRETOL 800 is used to treat epilepsy, specifically partial-onset seizures, in adults. It can be prescribed as a monotherapy for adults newly diagnosed with epilepsy or as an add-on (adjunctive) therapy for adults, adolescents, and children over 6 years of age who have partial-onset seizures, with or without secondary generalization.

How does ZEFRETOL 800 work?

ZEFRETOL 800 contains Eslicarbazepine (Eslicarbazepine acetate), an anti-epileptic drug. It works by targeting and blocking voltage-gated sodium channels in the nerve cells of the brain. This action stabilizes hyperexcited neurons, reducing abnormal electrical activity that leads to seizures, thereby preventing or reducing the frequency of epileptic episodes.

What is the usual dosage of ZEFRETOL 800?

The recommended initial dosage for ZEFRETOL 800 is typically 400 mg once daily. For some patients, treatment may begin at 800 mg once daily if a rapid reduction in seizures is needed and the increased risk of initial side effects is acceptable. The dosage is usually increased in weekly increments of 400 mg to 600 mg, based on the patient's clinical response and tolerability, to a maintenance dosage of 800 mg to 1600 mg once daily. It should be taken orally with or without food, preferably at the same time each day, and swallowed whole without crushing or chewing.

What are the possible side effects of ZEFRETOL 800?

Common side effects include dizziness, sleepiness, nausea, vomiting, headache, diarrhea, fatigue, blurred or double vision, difficulty concentrating, a sensation of unsteadiness, and skin rashes. It can also cause decreased appetite and, in some cases, low sodium levels in the blood (hyponatremia). More serious, but less common, side effects can include suicidal thoughts or behavior, severe allergic reactions, and issues with liver or kidney function.

Is ZEFRETOL 800 safe during pregnancy or breastfeeding?

ZEFRETOL 800 should be used with caution during pregnancy and only if clearly necessary, as it may be unsafe and cause harmful effects to the unborn baby. It is generally not recommended for use in breastfeeding women because the medicine passes into breast milk. If used, a doctor should closely monitor the infant for any side effects like drowsiness or inadequate weight gain. It is crucial to consult your doctor to weigh the potential benefits against the risks in both situations.

Can ZEFRETOL 800 be taken with other medications?

ZEFRETOL 800 can interact with several medications. These include other anti-epileptic drugs (such as carbamazepine, oxcarbazepine, phenytoin, and phenobarbital), hormonal contraceptives (which may have reduced effectiveness), certain cholesterol-lowering drugs (like simvastatin, rosuvastatin), blood thinners (warfarin), antidepressants (amitriptyline), diuretics, beta-blockers, and antiarrhythmics. Always inform your doctor about all prescription and non-prescription medications, herbal supplements, and vitamins you are taking to avoid potential interactions.

What precautions should be taken while using ZEFRETOL 800?

Precautions include:

• Driving and operating machinery: ZEFRETOL 800 may cause dizziness, drowsiness, and visual disturbances, so avoid driving or operating heavy machinery until you know how the medicine affects you.
• Abrupt discontinuation: Do not stop taking ZEFRETOL 800 suddenly, as this can increase the frequency of seizures. If discontinuation is necessary, your doctor will gradually reduce the dose.
• Medical conditions: This medicine is not recommended for patients with severe liver or kidney disease, certain heart rhythm disorders (second- or third-degree heart block), or known allergies to Eslicarbazepine. Use with caution in patients with heart failure, a history of seizures, blood problems (like anemia), or a pacemaker.
• Mental health: Patients should be monitored for any unusual changes in mood or behavior, including new or worsening depression or suicidal thoughts.
• Sodium levels: Your doctor may advise regular monitoring of your blood sodium levels due to the risk of hyponatremia.
• Alcohol: The safety of consuming alcohol with ZEFRETOL 800 is unknown; consult your doctor.

What happens if a dose of ZEFRETOL 800 is missed?

If you miss a dose of ZEFRETOL 800, take it as soon as you remember. However, if it is almost time for your next scheduled dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one.

How should ZEFRETOL 800 be stored?

ZEFRETOL 800 should be stored at room temperature, typically below 30°C (or between 10ºC and 25ºC), in a dry place. Keep it protected from direct light and moisture, and store it in its original packaging. Always keep this medicine out of the sight and reach of children.
